  Title:   Los Angeles Rooftop Albedo | Berkeley Lab  
  Archival URL:  
  Live URL:  
  Coverage:   November 22, 2016 - November 22, 2016  
  Description:   At noon on a clear summer day in the United States, a flat surface receives about 1000 watts of sunlight per square meter. Traditional dark roofs strongly absorb this sunlight, heating both the building and the surrounding air. This increases energy use in air conditioned buildings, and makes non-air conditioned buildings less comfortable. Hot dark roofs also aggravate urban heat islands by warming the air flowing over the roof, and contribute to global warming by radiating heat into the atmosphere.
